Silica Spray Sealant #50


Protect your boat with our Silica Spray Sealant #50. Its ceramic-style hydrophobicity and protection work for any boat or watercraft. Unlike a spray wax or detailer, Silica Spray Sealant is oil-based and filled with SiO2 polymers that begin to cure one hour after application and fully cure in 24 hours to provide a hard layer of SiO2 protection that lasts months.

Specifically designed for the marine environment, Silica Spray Sealant #50 wraps treated surfaces like gel coat, glass, paint and metal in a layer of hydrophobic, cross-linking polymers that bond to the surface and are resistant to most cleaners and the elements. Your boat will look glossier and feel silkier as it repels water and dirt, making it simple to clean after a long day on the water.
